The PDF file contains a critical heuristic firing for a malicious redirector link. The embedded URL, https://ttraff.cc/wix?keyword=react+native+elements+header, is the primary indicator of malicious activity. While no scripts were extracted, the presence of this malicious URL strongly suggests the PDF is designed to lure users to a harmful site. The document body appears to be corrupted or heavily obfuscated, preventing analysis of its direct content.

Heuristics 2

  • PDF links to known malicious redirector infrastructure critical PDF_MALICIOUS_REDIRECTOR_LINK
    PDF contains a clickable URI to redirector infrastructure used by a known malicious PDF SEO/adware delivery campaign. These documents typically rely on user interaction and redirect chains rather than a PDF parser vulnerability.
  • Embedded URL info EMBEDDED_URL
    One or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.
